one of the battery tabs wasnt properly welded
i bought this for a nose hair trimmer, to replace the old battery. after installing it the battery charge it shipped with drained & then it wouldnt accept a charge. i couldnt figure out what was wrong, but after looking closer, i noticed the - battery tab's electric spot weld hadnt held. the heat shrink they put over the tabs had melted to the negative battery end, which held the tab in place, and so i didnt notice until looking closer. i had to solder the tab on correctly & now it works fine. ive bought several tenergy products over the last 10yrs, and i wasnt happy with this purchase, it didnt live up to what ive grown to expect.
